    A country is big if it has an area of bigger than 3 million square km or a population of more than 25 million.
   </p>
   <p>
    Write a SQL solution to output big countries' name, population and area.
   </p>
   <p>
    For example, according to the above table, we should output:
   </p>

   <p>
    如果一个国家的面积超过300万平方公里，或者人口超过2500万，那么这个国家就是大国家。
   </p>
   <p>
    编写一个SQL查询，输出表中所有大国家的名称、人口和面积。
   </p>
   <p>
    例如，根据上表，我们应该输出:
   </p>
   <pre>+--------------+-------------+--------------+
| name         | population  | area         |
+--------------+-------------+--------------+
| Afghanistan  | 25500100    | 652230       |
